Isizukulwana esikhulu esilandelayo se-USB (i-Universal Serial Bus) iya kuba yi-USB 4, okanye uhlobo lwe-USB4, Kwaye iya kubonelela ngezincedisi ezininzi, ezinje ngeThunderbolt 3 inkxaso kunye nemilambo efikelela kwi-40 Gbps.
Okwangoku, le 2019 Iinguqulelo ezintsha (kunye ezininzi) ze-USB 3.x ezifikelela kwi-20 Gbps. Ukuhanjiswa kwedatha. Okona kutshanje, i-USB 3.2 yeGen 2 × 2 inguqu eboniswe nge-2019 efanayo, njenge-USB 4.
I-USB 4 yaziswa ngo-Matshi 2019 ngomboniso wenkqubo ezakuba yiyo kwaye ngaphandle kokubhengeza nawuphi na umhla oza kubakho ngawo.. Nangona kunjalo, amahemuhemu abonakala esalatha Ngo-2020 besele siza kubona izixhobo ezine-USB 4 kwizidibanisi ze-USB-C. Ewe kunjalo, ukuphela kwe-2020, ke kuya kufuneka silinde ngaphezulu konyaka ukubabona kwintengiso.
I-Apple linyathelo elinye phambili kule nkalo. Izihlanganisi ze-USB-C kwiimodeli zayo ezintsha zeMac ziThunderbolt 3, ke iyayixhasa ukuya kuthi ga kwi-40 Gbps. Ukuhanjiswa kwedatha nezinye izixhobo ezihambelanayo. Ngaphandle koko, kunyeIsinxibelelanisi esifanayo se-USB-C kwiiMacs ikwayi-USB 3.1 Gen 2 kwaye ixhasa ukuya kuthi ga kwi-10 Gbps.
Izihlanganisi zeMac zangoku ziyahambelana ne-USB 4 njengoko le nguqulo ye-USB iya kusekelwa kwiThunderbolt 3 kwaye iza kusebenzisa uhlobo lwezihlanganisi ze-USB-C.
I-USB 4 kunye netekhnoloji yayo inokwenza ukuba 2020 unyaka apho, ekugqibeleni, i-USB-C yandiswa njengesixhobo sokudibanisa izixhobo esithandwayo kwaye ayisiyomveliso ye-Apple kuphela (engekho kwiiMacs kuphela, kodwa nakwiPad Pro entsha eziyisebenzisa njengesihlanganisi ekuphela kwayo) kunye nezinye izixhobo ezizezinye ezivela kwezinye iimveliso, ngakumbi kwii-mobiles eziphezulu.
I-Apple kunye ne-Intel benze umsebenzi omninzi kwiThundebolt kwaye kubonakala ngathi i-USB imiselwe ukuba iwele kwizibonelelo ezinikezelwa yile teknoloji kule ikhoyo ngoku. Kodwa, okwangoku, kufuneka silinde.
